#1 I can answer to. There is no significant technical difference between AWS "MarketPlace" AMI's and installing your own MarkLogic onto EC2. There are 2 variants of the AWS MarketPlace AMI's a "BYOL" and a "Paid" version. The software pre-installed on them is the same. (Marklogic + all prerequisites). Its essentially the same as if you started with a stock AMI and then installed MarkLogic via RPM.
The CloudFormation scripts provide have the MarketPlace AMI's in them but you can replace those with your own AMI's and they have the same functionality even if you installed ML yourself. So the transition from MarketPlace AMI to your own fully customized AMI is quite smooth. You could start with the "BYOL" Marketplace AMI to test things out (with a developer license), witch to the "Paid" AMI for production then at some point in the future decide to get a long term License and switch back to either the "BYOL" AMI (using your production license) or customize the BYOL AMI or build one from scratch all while maintaining the features of CloudFormation and Managed clusters. Since nothing on the base AMI is configured differently, only your attached EBS volume, you can fairly easily switch between AMI's (Marketplace, customized or fully custom). Do beware that switching core OS's has a few challenges once you have created forests as the device naming differs between different OS's on AWS so it may take some handholding to switch from say Amazon Linux to RedHat or CentOS while maintaining data. I would advise against that, if you do something as drastic as switching core OS to do a backup (likely to S3) and reconfigure your cluster from scratch. The Managed Cluster features are very significant even for single hosts and come without extra licensing charges and are only available on AWS hosted ML. http://developer.marklogic.com/products/aws #2 - I don't know of any other hosted virtualization platforms which ML is tested against (besides AWS and VmWare), but I may be wrong. I do know that the Managed Cluster feature is only available on AWS at this time.

I've a few questions: 1) Can anyone comment on using the AWS pre-configured instances of MarkLogic vs having your own licence (being a direct MarkLogic customer) and leasing your own EC2 (and maybe S3) services? The canned solutions fro AWS seem interesting as a cloud solution for a client is likely the final solution, but if they use the AWS MarkLogic version and then decide to migrate away(and have not tied themselves into other AWS services), they have the future overhead of a licence. This scenario is theoretical, but it would be a cost to consider. So, having a licence from MarkLoic and a support contract from MarkLogic even on AWS seems like a possible solution. 2) Can anyone suggest another cloud-based hosting provider for MarkLogic. In this case, it would likely have to be a provides of VmWare products because I believe MarkLogic is still tested on only AWS and VmWare for virtualized environments.I would prefer a company that I can configure and get a cost-estimate online without going through rounds of conversations with a consultant/sales engineer.
